System of settlement transaction and method

ABSTRACT

In a settlement transaction system or settlement transaction method using the system, the system includes a content providing server conducting a digital broadcast, for example, for a CS broadcast, a BS broadcast, a CATV, or a broadcast using ground waves; a settlement server to execute settlement transaction or settlement transaction, an order placement managing server to execute order placement processing, and an order managing server which receives an order of a request from a user to purchase articles and which sends an associated indication to the settlement server and the order placement managing server according to information of the order. The user operates a terminal in which an IC card communication application to communicate with an IC card is only installed. It then becomes possible to reduce a load imposed onto the system in association with a change to an existing digital broadcast system.

The present application claims priority from Japanese application JP 2003-380629 filed on Nov. 11, 2003, the content of which is hereby incorporated by reference into this application.

BACKGROUND OF THE INVENTION

The present invention relates to a settlement transaction system and a settlement transaction method, and in particular, to a settlement transaction system and a settlement transaction method, for example, using an integrated-circuit (IC) card via a network.

Heretofore, digital broadcast signals used in various facilities such as a communications satellite (CS), a broadcast satellite (BS), a cable television (CATV), and a broadcasting system using ground waves are received by a receiver, for example, a dedicated tuner such as a settop box (STB) and a television terminal integrally included in such a tuner. The settop box and the television terminal or set can bidirectionally communicate data with an external server using a communication line. Therefore, it is possible to implement a method of and a system for providing services using the bidirectional communication such as a system of, for example, online television (TV) shopping. For example, JP-A-2002-24578 describes a method and a system using the bidirectional communication for the online TV shopping to provide services of ordering and delivering articles or items periodically purchased by customers.

For example, JP-A-2003-16361 describes a settlement transaction method and a settlement transaction system which are associated with online shopping and which are capable of coping with various settlement schemes or methods using, for example, a credit card and a debit card to easily and safely conduct online settlement from various terminals via a network. As specifications of processing procedure for the transaction procedure, there has been, for example, EMV (Europay, Mastercard and Visa) specifications. The specifications include “Type Approval” as a terminal approval scheme. The Type Approval has two levels, i.e., Level 1 and Level 2. The functions required therein have been defined by “EMV 2000 Integrated Circuit Card Specification for Payment Systems” and “EMV 1996 Integrated Circuit Card Specification for Payment Systems”.

According to the prior art of JP-A-2002-24578, in the method of and a system for providing services of ordering and delivering articles periodically purchased by customers using the bidirectional communication for the online TV shopping, one server executes processing of order placement, processing of order acceptance, processing of settlement or settlement transaction, processing of personal authentication of the customer, and processing of item information production to produce, for example, an image of an article for sale. Therefore, in a case in which an existing settlement scheme or way of the server copes with only a credit card, if there occurs an event in which a debit card is also specified as a settlement scheme, the server needs to obtain a settlement application coping with settlement using a debit card. However, since the server includes applications not related to settlement, it is difficult, in consideration of the human power of maintenance and the cost for installation of the new application, to additionally install a settlement application for settlement using a debit card.

The settlement transaction method and the settlement transaction system of JP-A-2003-16361 are suitable for electronic commerce (EC) using a network. However, a terminal of the user in this system needs to include settlement applications only for predetermined settlement methods. Therefore, to increase a settlement method, it is necessary to obtain a settlement application coping with the new settlement method.

SUMMARY OF THE INVENTION

It is therefore an object of the present invention to provide a settlement transaction system using a digital broadcast and a settlement transaction method using an IC card via a network. The system includes a content providing server conducting a digital broadcast, for example, for a communications satellite (CS) broadcast, a broadcast satellite (BS) broadcast, a cable television (CATV), or a broadcast using ground waves; a settlement server to execute settlement transaction or settlement transaction, an order placement managing server to execute order placement processing, and an order managing server which receives an order of a request from a user or a customer to purchase articles or items and which sends an associated indication to the settlement server and the order placement managing server according to information of the order. In the system, the user operates his or her terminal in which a settlement application to execute settlement transaction or processing is not installed, but only an IC card communication application to communicate with an IC card is installed. This advantageously reduces a load imposed onto the system in association with a change to an existing digital broadcast system.

According to the present invention, there is provided a settlement transaction system having high usability.

Referring next to FIG. 11, description will be given of operation of the embodiment.

FIG. 11 is a flowchart of a processing flow in which the embodiment of the system executes settlement transaction when a user selects a desired article using the settop box 200 from a TV shopping program of a digital broadcast.

There also exist other cases, for example, a case in which the user only televiews a digital broadcast program without desiring purchase of articles and a case in which the user interrupts settlement transaction after selecting articles to be purchased using the settop box 200. Therefore, the processing flow of FIG. 11 can be terminated at any intermediate step in the flow. However, the event of such termination is not shown in the drawings and will not be described.

In step S1200, the content providing server 100 sends a content including item information such as an image of items put for sale in a TV shopping program via the dedicated cable 500 to the settop box 200 of each user according to a predetermined broadcasting method.

In step S1201, the settop box 200 receives the content and displays the content of item for sale on a predetermined display device such as a television terminal. This embodiment uses a television set as the display device.

In step S1201, the user televiews on the television set the content of item for sale sequentially sent from the server 100. When the shopping program displays items desired by the user, the process goes to step S1202.

In step S1202, the user operates the key-in unit 601 a of the settop box 200 to display the items on the television screen and determines the quantity of the items to be purchased and the settlement type for the purchase. In this situation, the system displays a screen image shown as an example in FIG. 13.

In step S1201, when the user selects “O.K.” in the screen of FIG. 13 using the key-in unit 601 a of the settop box 20, control goes to step S1203.

In step S1203, the settop box 200 creates an item selection text 1000 and sends the text from the data communication unit 614 to the order managing server 101. In this operation, the text 1000 includes information data of an item number 901, a unit price 902, a quantity 903, a settlement amount 904, and a settlement type 905 of the articles desired by the user for the purchase.

In step S1203, the order-managing server 101 receives the text 1000 from the settop box 200, and then control goes to step S1204.

In-step S1204, the server 101 creates a settlement confirmation text 1003 and sends the text from the network communication unit 700 to the content providing server 100. Information data of the text 1003 is substantially the same as that of the item selection text 1000.

In step S1204, the server 100 receives the text 1003 from the order managing server 101, and the process goes to step S1205.

In step S1205, the content providing server 100 sends to the settop box 200 predetermined content information to display a settlement confirmation screen as shown in FIG. 14.

In step S1205, the settop box 200 receives the predetermined content information to display the settlement confirmation screen from the server 100, and control goes to step S1206.

In step S1206, the settop box 200 receives the content and displays the settlement confirmation image of FIG. 14 on the TV screen, and the process goes to step S1207.

In step S1207, the user watches the settlement confirmation screen of FIG. 14 to confirm detailed information of items to be purchased. If the confirmation is correctly finished, the user selects “Order” in the screen using key-in unit 601 a of the settop box 20. Then, control goes to step S1208.

In step S1208, the settop box 200 creates a confirmed information text 1005 and sends the text from the data communicating unit 614 to the order managing server 101. The text 1005 includes information data of an item number 901, a unit price 902, a quantity 903, a settlement amount 904, and a settlement type 905 of the articles which are desired by the user for the purchase and which have been confirmed by the user on the settlement confirmation screen of FIG. 14.

If the user does not desire settlement in step S1207 and selects “Cancel” using key-in unit 601a of the settop box 20, the system interrupts the processing for the purchase of items. However, for easy understanding of operation of the embodiment, the user can only select “Cancel” if the detailed information of items desired by the user for the purchase includes an error. However, the processing procedure may include an additional step to correct the detailed information of items desired by the user for the purchase.

In step S1208, the order managing server 101 receives the confirmed information text 1005 from the settop box 200, and the process goes to settlement (1) enclosed by dot-and-dash lines. Settlement (1) will be described in detail later in conjunction with FIG. 12. In the procedure, settlement (1) starts when the server 101 sends a settlement start text 1007 to the settlement server 102. Thereafter, the settlement transaction 1210 is executed by the IC card 201, the settop box 200, the settlement server 102, and the online settlement server 300 a. After the settlement transaction 1210 is finished, when the server 101 receives a settlement completion text 1009 from the settlement server 102, settlement (1) is finished. Control then goes to step S1214.

In step S1214, the order managing server 101 generates a completion confirmation text 1011 and sends the text from the network communication unit 700 to the content providing server 100. The text 1011 includes data items similar to those of the confirmed information text 1005. The text 1011 includes a transaction number which is an identifier uniquely assigned by the settlement transaction 1210.

In step S1214, the content providing server 100 receives the completion confirmation text 1011 from the order managing server 101, and the process goes to step S1215.

In step S1215, the server 100 sends to the settop box 200 predetermined content information to display a settlement completion screen shown by way of illustration in FIG. 15.

In step S1215, when the settop box 200 receives the content information to display the settlement completion screen, control goes to step S1216.

In step S1216, the settop box 200 receives the content and displays the settlement completion screen of FIG. 15 on the TV screen, and the process goes to step S1217.

In step S1217, the order managing server 101 generates a order placement text 1013 and sends the text from the network communication unit 700 to the order placement managing server 103. The text 1013 includes data items similar to those of the completion confirmation text 1011. The text 1013 includes a customer identifier 800 corresponding to the terminal identifier 1002 obtained from the customer database 104.

In step S1217, the server 103 receives the order placement text 1013 from the order placement managing server 103, and control goes to step S1218.

In step S1218, the server 103 executes predetermined order placement processing via the network communication unit 700 for the order acceptance server 400 a under control of a supplier or a company selling items desired by the user.

It is also possible that the order placement managing server 103 executes predetermined order placement processing via the network communication unit 700 for the order acceptance server 400 a under control of a content providing company creating and providing contents of the TV shopping. Thereafter, the content providing company executes predetermined order placement processing for the order acceptance server 400 a under control of the supplier selling items desired by the user.

In step S1218, when the order placement managing server 103 completely executes the order placement processing, the process goes to step S1219.

In step S1219, the server 103 creates an order placement completion text 1015 and sends the text from the network communication unit 700 to the order managing server 101.

In step S1219, the server 101 receives the text 1015 from the order placement managing server 103, and control goes to step S1220.

In step S1220, the order managing server 101 stores in the order placement database 105 the transaction number 900, the item number 901, the unit price 902, the quantity 903, the settlement amount 904, the settlement type 905, and the monthly total amount 906 obtained from the order placement information for which the settlement transaction and the order placement processing have been completed.

When an order is received as a result of the order placement processing, the supplier delivers to the user the items desired by the user as above.

FIG. 12 shows a flowchart of the settlement transaction 1210 executed using the IC card 201, the settop box 200, the settlement server 102, and the online settlement server 300 a when the settlement type is “IC card credit”.

At timing of step S1209 of FIG. 11, the order managing server 101 sends a settlement start text 1007 to the settlement server 102.

In step S1209, the server 102 receives the text 1007 from the order managing server 101, and the process goes to step S1300.

In step S1300, the settlement server 102 initiates the settlement information creating program 704 stored in the storage 702, and control goes to step S1301.

In step S1301, the server 102 sends an IC card communication program initiation text 1105 to the settop box 200.

In step S1301, the settop box 200 receives the text 1105 from the settlement server 102, and the process goes to step S1302.

In step S1302, the settop box 200 initiates an IC card communication processing program 607 in the storage 605 and proceeds to step S1303.

In step S1303, the settop box 200 sends an initiation completion text 1107 to the settlement server 102.

In step S1303, the server 102 receives the text 1107 from the settop box 200, and control goes to settlement transaction 1210.

In the settlement transaction 1210, the settlement server 102 repeatedly executes communication processing with the IC card 201 and the online settlement server 300 a according to a predetermined procedure to resultantly execute the settlement transaction. The predetermined procedure of settlement transaction conforms to, for example, specifications for credit and debit transaction of Europay, Mastercard, and Visa (EMV) stipulating a processing procedure and text items for IC card credit.

In the following description, the settlement transaction will be described according to the EMV specifications for easy understanding of the settlement processing.

The EMV specifications include “type approval” as a terminal approval scheme. The type approval has two levels, i.e., level 1 and level 2. When the EMV type approval is applied to the embodiment, functions at level 1 are assigned to the settop box 200 of FIG. 2 and functions at level 2 are assigned to the settlement server 102 of FIG. 5.

“EMV2000 Integrated Circuit Card Specification for Payment Systems” and “EMV'96 Integrated Circuit Card Specification for Payment Systems” stipulate the functions at levels 1 and 2 of EMV type approval.

In step S1304, the settlement server 101 collects text items required by the EMV specifications to form an IC card communication command 1102 to generate an IC card communication text 1100 including the command 1102 and sends the text 1100 to the settop box 200.

For the IC card communication command 1102, the settlement server 101 may use, for example, an application protocol data unit (APDU) to create the IC card communication text 1100.

In step S1304, when the settop box 200 receives the text 1100 from the server 101, control proceeds to step S1305.

In step S1305, the step S1305 sends the IC card communication command 1102 of the text 1100 to the IC card 201.

In step S1305, the IC card 201 receives the command 1102 from the settop box 200, and control goes to step S1306.

In step S1306, the IC card 201 sends to the settop box 200 an IC card communication response 1105 in reply to the command 1102.

In step S1306, the settop box 200 receives the response 1105 from the IC card 201, and the process goes to step S1307.

In step S1307, the settop box 200 creates an IC card communication reply text 1103 including the response 1105 received from the IC card 201 and sends the text 1103 to the settlement server 102.

For the response 1105, the settop box 200 may use, for example, the application protocol data unit to create the text 1103.

If it is required in the settlement procedure for the user to input a secret number, the user inputs his or her secret number from the key-in unit 601a. The cryptograph unit 620 encrypts data of the secret number into encrypted data. In step S1307, the settop box 200 creates an IC card communication reply text 1103 including the encrypted data of the secret number and sends the text 1103 to the settlement server 102.

It is also possible that the secret number data inputted from the key-in unit 601 a is not encrypted but is directly set to the IC card communication reply text 1103 to be sent to the settlement server 102. In this case, the cryptograph unit 620 may be removed from the settop box 200.

Also in step S1307, the settlement server 101 treats the IC card communication response 1105 of the text 1103 as an EMV reply text item.

Thereafter, the system repeatedly executes steps S1304 to S1307 according to a predetermined processing procedure of EMV.

In steps S1308 and S1309, the settlement server 102 repeatedly communicates with the online settlement server 300 a using predetermined text items of EMV.

When the processing is completely finished in the processing procedure of EMV, the IC card settlement transaction 1210 is terminated and control goes to step S1213.

In step S1213, the settlement server 102 sends a settlement completion text 1009 to the order managing server 101.

The predetermined processing procedure of EMV conforms to, for example, the IC credit standard, i.e., “EMV2000 Integrated Circuit Card Specification for Payment Systems” or “EMV'96 Integrated Circuit Card Specification for Payment Systems”. The settlement transaction of the settlement server includes processing and judgement to be conducted by the application protocol data unit (APDU) associated with the specification.

In the predetermined processing procedure of EMV, if the settlement program of the settlement server 102 requests the user to input a secret number, the user inputs a secret number from the key-in unit 601 a shown in FIG. 2. In this situation, if the settlement is conducted through online processing, the settlement server 102 sends the secret number to the settlement transaction server 300 a or 300 b. If the settlement is conducted through offline processing, the settlement server 102 sends the secret number via the settop box 200 to the IC card 201.

It is also possible in the operation that the cryptograph unit 620 of the settop box 200 encrypts the secret number.

The settop box 200 may conduct the settlement without encrypting the secret number. In this case, it is not necessarily required to arrange the cryptograph unit 620 in the settop box 200.

In the description, the settop box 200 integrally includes the IC card 201 for the settlement transaction as shown in FIG. 2. However, it is also possible to integrate the IC card for settlement in the remote control 202 as shown in FIG. 3. In this situation, as can be seen from FIG. 3, the remote control 202 includes the IC card communication processing program 607 to execute communication processing with the IC card. In the settlement transaction in this configuration, the remote control 202 executes as shown in FIG. 16 the processing of steps S1302, S1303, S1305, and S1307 executed by the settop box 200 in FIG. 12.

In step S1301, the settop box 200 sends the IC card communication program initiation text 1105 received from the settlement server 102 to the remote control 202 via the narrow-band wireless communication.

In step S1303, the remote control 202 transmits an initiation completion text 1107 via the narrow-band wireless communication to the settop box 200.

In step S1304, the IC card communication text 1100 from the settlement server 102 is sent via the narrow-band wireless communication to the remote control 202.

In step S1305, the remote control 202 sends the text 1100 via the wireless communication to the settop box 200.

When the texts shown in FIGS. 10A to 10D are used between the remote control 202 and the settop box 200, each text includes the terminal identifier 1002 including an identifier uniquely assigned to the remote control 202.

In the settlement procedure, if it is required for the user to input a secret number in response to a request from the settlement program 704 of the settlement server 102, the user inputs a secret number from the key-in unit 601 b shown in FIG. 3. In this case, if the settlement is conducted through online processing, the settlement server 102 sends the secret number to the settlement transaction server 300 a or 300 b. If the settlement is conducted through offline processing, the settlement server 102 sends the secret number via the settop box 200 and the remote control 202 to the IC card.

Also in this case, it is possible that the cryptograph unit 620 of the settop box 200 encrypts the secret number.

The settop box 200 may conduct the settlement without encrypting the secret number. In this situation, it is not necessarily required to arrange the cryptograph unit 620 in the settop box 200.

Moreover, in the first embodiment, the portable terminal 203 may integrally include the IC card for the settlement transaction as shown in FIG. 4. The portable terminal 203 includes the IC card communication processing program 607 to conduct communication processing with the IC card also in this case as shown in FIG. 4. The settlement transaction in this configuration is similar to that of the remote control 202 shows as an example in FIG. 16. In this case, the processing conducted by the remote control 202 is similarly conducted by the portable terminal 203.

In the settlement procedure, if it is required for the user to input a secret number in response to a request from the settlement program 704 of the settlement server 102, the user inputs a secret number from the key-in unit 601 c shown in FIG. 4. In this case, if the settlement is conducted through online processing, the settlement server 102 sends the secret number to the settlement transaction server 300 a or 300 b. If the settlement is conducted through offline processing, the settlement server 102 sends the secret number via the settop box 200 and the remote control 203 to the IC card.

Also in this case, it is possible that the cryptograph unit 620 of the settop box 200 encrypts the secret number.

The settop box 200 may conduct the settlement without encrypting the secret number. In this situation, it is not necessarily required to arrange the cryptograph unit 620 in the settop box 200.

Next, description will be given of a second embodiment.

FIG. 17 shows an overall configuration of a second embodiment of a settlement transaction system using a digital broadcast according to the present invention.

In this configuration for bidirectional communication, data can be communicated between the settop box 200 and the content providing server 100 via a dedicated cable.

To conduct the conventional accounting operation, the content providing server 100 includes an accounting database 106.

In FIG. 17, the same constituent components as those of FIG. 1 are assigned with the same reference numerals and description thereof will be avoided.

FIG. 18 shows in a flowchart a processing flow in which the system of the embodiment conducts settlement transaction in consideration of the conventional accounting operation when a user selects a desired article using the settop box 200 from a TV shopping program of a digital broadcast.

The procedure from step S1200 to S1208 is substantially the same as that shown in FIG. 11.

However, in the text layouts shown in FIG. 9, the settlement type 905 as information data of each text includes data indicating an accounting settlement depending on cases according to the second embodiment of the present invention.

For example, when the user selects the accounting settlement as the settlement scheme, the settlement type 905 includes data indicating the accounting settlement.

In step S1700, the order managing server 101 makes a check for the settlement type 905 in the confirmed information text 1005 received via the content providing server 100 from the settop box 200. If the settlement type 905 is “credit”, the system executes processing according to the flow shown in FIG. 12 and control goes to step S1214.

If the settlement type 905 is “accounting settlement”, the order managing server 101 executes predetermined accounting processing 1702. The server 101 stores the transaction number 900, the item number 901, the unit price 902, the quantity 903, the settlement amount 904, the settlement type, and the monthly total amount 906 in the accounting database 106 with a correspondence established between these items and the customer identifier 800 associated therewith.

When the accounting processing 1702 is completely finished, control goes to step S1214.

The processing procedure from step S1214 to step S1220 is substantially the same as that shown in FIG. 11.

In step S2108, the server 100 receives the text 2007 from the order managing server 101 and control goes to step S2109.

In step S2109, the server 100 transmits to the settop box 200 predetermined content information to display a cancellation confirmation screen shown in FIG. 27.

In step S2109, when the settop box 200 receives the predetermined content information from the server 100, control goes to step S2110.

In step S2110, the settop box 200 displays the cancellation confirmation screen of FIG. 27 on the TV screen using the content from the settop box 200.

In step S2110, the user visually checks the screen and confirms detailed information of the item for settlement cancellation. If the detailed information is correct, the user selects “O.K.” from the screen using the key-in unit 601 a of the settop box 200 and the process goes to step S2111.

In step S2111, the settop box 200 creates a cancellation information text 2009 and sends the text from the data communication unit 614 to the order managing server 101.

In step S2111, the server 101 receives the text 2009 from the settop box 200 and control goes to cancellation processing. The processing corresponds to the settlement transaction in the frame (1) of dot-and-dash lines shown in FIG. 11. In the following description, the settlement transaction of FIG. 11 is used in place of the cancellation processing for easy understanding of the processing.

The procedure of the cancellation processing is started when the server 101 sends a cancellation start text 2011 to the settlement server 102. Thereafter, the cancellation processing S2114 is executed by the IC card 201, the settop box 200, the settlement server 102, and the online settlement server 300 a. The cancellation processing is executed according to a predetermined cancellation processing procedure associated with the settlement type specified at purchase of the item.

After the cancellation processing S2114 is finished, when the order managing server 101 receives a cancellation completion text 2013 from the settlement server 102, the cancellation processing is finished. Thereafter, control goes to step S2118.

In step S2118, the server 101 creates a cancellation completion confirmation text 2013 and sends the text from the network communication unit 700 to the content providing server 100.

In step S2118, the server 100 receives the text 2013 from the order managing server 101 and control proceeds to step S2119.

In step S2119, the server 100 sends to the settop box 200 predetermined content information to display a purchase cancellation completion screen shown in FIG. 28.

In step S2119, when the settop box 200 receives the predetermined content information from the server 100, the process goes to step S2120.

In step S2120, the settop box 200 receives the content and displays the purchase cancellation completion screen on the TV screen, and then control goes to step S2121.

In step S2121, the order managing server 101 creates an order placement cancellation text 2017 and sends the text from the network communication unit 700 to the order placement managing server 103.

In step S2121, the server 103 receives the text 2017 from the order managing server 101 and control goes to step S2122.

In step S2122, the server 103 executes via the network communication unit 700 predetermined order placement cancellation processing for the order acceptance server 400 a under control of the supplier of articles to be purchased by the user.

Alternatively, the order placement cancellation may be conducted as follows. The order placement managing server 103 executes via the network communication unit 700 predetermined order placement cancellation processing for the order acceptance server 400 b under control of the content providing company creating and providing contents of TV shopping. Thereafter, the content providing company executes predetermined order placement cancellation processing for the order acceptance server 400 a under control of the supplier of articles to be purchased by the user.

In step S2122, when the order placement managing server 103.finishes the order placement cancellation processing, control goes to step S2123.

In step S2123, the server 103 creates an order placement cancellation completion text 2019 and sends the text from the network communication unit 700 to the order managing server 101.

In step S2123, the server 101 receives the text 2019 from the order placement managing server 103 and control proceeds to step S2124.

In step S2124, the server 101 deletes the order placement information items for which the order placement cancellation processing is finished. That is, the server 101 deletes the transaction number 900, the item number 901, the unit price 902, the quantity 903, the settlement amount 904, the settlement type 905, and the monthly total amount 906 from the order placement list corresponding to the customer identifier 800.

The cancellation processing described above conforms to, for example, the IC credit standard “EMV2000 Integrated Circuit Card Specification for Payment Systems” or “EMV'96 Integrated Circuit Card Specification for Payment Systems”. The settlement transaction of the settlement server includes processing and judgement to be conducted by the application protocol data unit (APDU) associated with the specification.

In the description of the settlement cancellation processing as in that of the first embodiment, the settop box 200 may integrally include, in the overall system configuration of the settlement transaction system using a digital broadcast, the IC card 201 for settlement as shown in FIG. 2. Or, the remote control 202 may integrally include the IC card 201 for settlement as shown in FIG. 3. Alternatively, the portable terminal 203 may include the IC card 201 for settlement as shown in FIG. 4.

In the first to third embodiments, the settop box 200 receives, in step S1201 of FIG. 11, the content from the content providing server 100 and displays the content of items on a predetermined display such as a TV screen. However, it is also possible that the settop box 200 communicates with the IC card 201 including the storage 611 a storing the personal information 612 to acquire the personal information 612. The settop box 200 then obtains age data from the information 612 and selects, using the age data, a content of items according to an age group of the user to resultantly display the content on a predetermined display such as a TV screen. It is also possible that the settop box 200 obtains address data from the information 612 and selects, using the address data, a content of items according to a district of the address of the user to resultantly display the content on a predetermined display such as a TV screen.

Data other than the age data and the address data may also be used. For example, according to the personal information 612 in the storage 611 a of the IC card 201, the settop box 200 may examine detailed items of the content sent from the content providing server 100 to appropriately display the detailed items on a predetermined display such as a TV screen.

When a limited number of items are offered for sale, it is possible that the order managing server 101 integrally includes a clock module to obtain, at start of settlement transaction, a date and/or time for each user desiring a purchase. According to information items of the data and/or the time, the server 101 determines the user to purchase the items. For example, the server 101 determines the user who can purchase desired items in an ascending order of the time value. That is, the user having an earlier time can purchase the items. For a user conducting the settlement during a time zone specified by a broadcasting company such as a content providing company or a CATV company, it may also possible to provide a particular service. For example, the value of points for the settlement is doubled for the user.

In the description of the first to third embodiments, the user selects a settlement type for purchased articles from the screen image of a predetermined display such as a TV screen. However, it is also possible that according to the settlement amount of articles purchased by the user, the settop box 200 automatically determines the settlement type and then requests the user to confirm the settlement type on the screen.

Additionally, when the item selection text 1000 and the confirmed information text 1005 are communicated between the settop box 200 and the order managing server 101 in the first to third embodiments, each text includes information data items such as an item number 901, a unit price 902, a quantity 903, and a settlement amount 904. However, it is also possible that the information data of each text includes only an item number 901. In this case, the order managing server 101 includes a database including item information such as an item number 901, a unit price 902, a quantity 903, and a settlement amount 904. If the item information is used, the server 101 makes a search for the item information using the item number 901 of each text.

When the settlement start text 1007 shown in FIG. 9 is used in the first to third embodiments, the text includes information data such as an item number 901, a unit price 902, a quantity 903, and a settlement amount 904. However, the text may include only a settlement amount 904.
